The National Women's Soccer League (NWSL) is the top-tier professional women's soccer league in the United States and Canada. Founded in 2013, the 2019 season, the last before COVID-19, saw an average 7,337 spectators among the 9 teams, the highest average attendance in league history. Its overall attendance in 2019 was also its highest ever, with 792,409 total. The overall attendance record was broken in the 2022 season, the first since 2019 to be relatively unaffected by COVID-19, with a total of 1,042,063. However, the per-game record from 2019 remains intact; the league had 10 teams in 2019 but expanded to 12 for 2022. The NWSL has the highest average attendance per game among all women's professional sports leagues in the United States.
